Who said they ever arrived. Since terraforming is such a long term progress, it is best to send the terraforming drones first, possibly manned. Maybe the terraforming fleet arrived, terraformed the planet, and then noticed the mainfleet wasn't arriving, or something else and they left. Hell, maybe we send those drones, I doubt the aliens could make the difference between robots and other lifeforms, and we ended up here with corrupted memories.
Thinking of it, for a colony ship we have/had barily any terraforming equiptment.
Yeah they could have bene using terraforming drones or vonneuman devices, just another automated system to terraform the planet. Yeah it is likely they never had more then a small colony at the very most.
Meinfreunde, you were mor or less ninja'd by zamara zee pony. He pretty much had the same explanation.
yeah I know i was writting in resposne just to eleborate more on the possibilities and diffrent scenerios, and why that ultimatly leads to war as thier most liekly cause for leaving.
I now think that the most likley scenerios would be exactly what 10ebbor10 said numbered for convienince, 1) either this was intended as our new home planet, and set up by drones in advance, 2)or the other species sent out drones or a very small terrafroming force in order to terraform the planet and the force was exterminated after it had setup the equipment, or 3) the drones moved on, or 4) the force wasn't exterminated but the fleet that was intended to colonize the planet was destroyed or diverted.
We need more archeaological information to be sure.
*quad ninja'd wow,
Can we get inside one of those station/satellites around the planet? Get a look at them from the inside without ruining them? Maybe it would shed some light.
seconded
We have a facility that re-arranges anything and everything atom by atom into what we need, I am pretty sure we have alot.
On another note I support ebbor and zamara regarding votes.
That's just standard colonising and repair equipment. If this ship had been intended to terraform things we would have had a lot more specialized equipment.
Yeah you would expect the ship that was intended to set up the second home world of humanity would have more than just one nano factory.
